Network Connection Problems

There may be a network connection problem if the LED on the
card's bracket does not light, or if you cannot access any network
resources from the computer. Check the following items before
contacting SMC Technical Support.
N Be sure you are using Category 5 cable for 100 Mbps
connections, and that the length of any cable does not exceed
100 m (328 ft).
N Inspect all network cables and connections. Make sure the
network cable is securely attached to the card's connector.
N Make sure the correct network card driver is installed for your
operating system. If necessary, try reinstalling the driver.
N Make sure the computer and other network devices are
receiving power. If you suspect a power outlet to be faulty,
plug another device into it to verify that it is working.
N If the the network card's speed or duplex mode has been
configured manually, check that it matches that of the attached
network device port. Note that it is recommended to set the
card to auto-negotiation when installing the network driver.
N The port on the network device that the card is attached to may
be defective. Try using another port on the device.
N If you cannot access a Windows or NetWare service on the
network, check that you have enabled and configured the
service correctly. If you cannot connect to a particular server,
ensure that you have access rights and a valid ID and password.
N If you cannot access the Internet, be sure you have configured
your system for TCP/IP.
